     * @ngdoc service
     * @name $resource
     * @requires $http
     *
     * @description
     * A factory which creates a resource object that lets you interact with
     * [RESTful](http://en.wikipedia.org/wiki/Representational_State_Transfer) server-side data sources.
     *
     * The returned resource object has action methods which provide high-level behaviors without
     * the need to interact with the low level {@link ng.$http $http} service.
     *
     * Requires the {@link ngResource `ngResource`} module to be installed.
     *
     * By default, trailing slashes will be stripped from the calculated URLs,
     * which can pose problems with server backends that do not expect that
     * behavior.  This can be disabled by configuring the `$resourceProvider` like
     * this:
     *
     * ```js
     app.config(['$resourceProvider', function($resourceProvider) {
       // Don't strip trailing slashes from calculated URLs
       $resourceProvider.defaults.stripTrailingSlashes = false;
     }]);
     * ```
     *
     * @param {string} url A parametrized URL template with parameters prefixed by `:` as in
     *   `/user/:username`. If you are using a URL with a port number (e.g.
     *   `http://example.com:8080/api`), it will be respected.
     *
     *   If you are using a url with a suffix, just add the suffix, like this:
     *   `$resource('http://example.com/resource.json')` or `$resource('http://example.com/:id.json')`
     *   or even `$resource('http://example.com/resource/:resource_id.:format')`
     *   If the parameter before the suffix is empty, :resource_id in this case, then the `/.` will be
     *   collapsed down to a single `.`.  If you need this sequence to appear and not collapse then you
     *   can escape it with `/\.`.
     *
     * @param {Object=} paramDefaults Default values for `url` parameters. These can be overridden in
     *   `actions` methods. If any of the parameter value is a function, it will be executed every time
     *   when a param value needs to be obtained for a request (unless the param was overridden).
     *
     *   Each key value in the parameter object is first bound to url template if present and then any
     *   excess keys are appended to the url search query after the `?`.
     *
     *   Given a template `/path/:verb` and parameter `{verb:'greet', salutation:'Hello'}` results in
     *   URL `/path/greet?salutation=Hello`.
     *
     *   If the parameter value is prefixed with `@` then the value for that parameter will be extracted
     *   from the corresponding property on the `data` object (provided when calling an action method).  For
     *   example, if the `defaultParam` object is `{someParam: '@someProp'}` then the value of `someParam`
     *   will be `data.someProp`.
     *
     * @param {Object.<Object>=} actions Hash with declaration of custom actions that should extend
     *   the default set of resource actions. The declaration should be created in the format of {@link
        *   ng.$http#usage $http.config}:
     *
     *       {action1: {method:?, params:?, isArray:?, headers:?, ...},
 *        action2: {method:?, params:?, isArray:?, headers:?, ...},
 *        ...}
     *
     *   Where:
     *
     *   - **`action`** â {string} â The name of action. This name becomes the name of the method on
     *     your resource object.
     *   - **`method`** â {string} â Case insensitive HTTP method (e.g. `GET`, `POST`, `PUT`,
     *     `DELETE`, `JSONP`, etc).
     *   - **`params`** â {Object=} â Optional set of pre-bound parameters for this action. If any of
     *     the parameter value is a function, it will be executed every time when a param value needs to
     *     be obtained for a request (unless the param was overridden).
     *   - **`url`** â {string} â action specific `url` override. The url templating is supported just
     *     like for the resource-level urls.
     *   - **`isArray`** â {boolean=} â If true then the returned object for this action is an array,
     *     see `returns` section.
     *   - **`transformRequest`** â
     *     `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` â
     *     transform function or an array of such functions. The transform function takes the http
     *     request body and headers and returns its transformed (typically serialized) version.
     *     By default, transformRequest will contain one function that checks if the request data is
     *     an object and serializes to using `angular.toJson`. To prevent this behavior, set
     *     `transformRequest` to an empty array: `transformRequest: []`
     *   - **`transformResponse`** â
     *     `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` â
     *     transform function or an array of such functions. The transform function takes the http
     *     response body and headers and returns its transformed (typically deserialized) version.
     *     By default, transformResponse will contain one function that checks if the response looks like
     *     a JSON string and deserializes it using `angular.fromJson`. To prevent this behavior, set
     *     `transformResponse` to an empty array: `transformResponse: []`
     *   - **`cache`** â `{boolean|Cache}` â If true, a default $http cache will be used to cache the
     *     GET request, otherwise if a cache instance built with
     *     {@link ng.$cacheFactory $cacheFactory}, this cache will be used for
     *     caching.
     *   - **`timeout`** â `{number|Promise}` â timeout in milliseconds, or {@link ng.$q promise} that
     *     should abort the request when resolved.
     *   - **`withCredentials`** - `{boolean}` - whether to set the `withCredentials` flag on the
     *     XHR object. See
     *     [requests with credentials](https://developer.mozilla.org/en/http_access_control#section_5)
     *     for more information.
     *   - **`responseType`** - `{string}` - see
     *     [requestType](https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType).
     *   - **`interceptor`** - `{Object=}` - The interceptor object has two optional methods -
     *     `response` and `responseError`. Both `response` and `responseError` interceptors get called
     *     with `http response` object. See {@link ng.$http $http interceptors}.
     *
     * @param {Object} options Hash with custom settings that should extend the
     *   default `$resourceProvider` behavior.  The only supported option is
     *
     *   Where:
     *
     *   - **`stripTrailingSlashes`** â {boolean} â If true then the trailing
     *   slashes from any calculated URL will be stripped. (Defaults to true.)
     *
     * @returns {Object} A resource "class" object with methods for the default set of resource actions
     *   optionally extended with custom `actions`. The default set contains these actions:
     *   ```js
     *   { 'get':    {method:'GET'},
 *     'save':   {method:'POST'},
 *     'query':  {method:'GET', isArray:true},
 *     'remove': {method:'DELETE'},
 *     'delete': {method:'DELETE'} };
     *   ```
     *
     *   Calling these methods invoke an {@link ng.$http} with the specified http method,
     *   destination and parameters. When the data is returned from the server then the object is an
     *   instance of the resource class. The actions `save`, `remove` and `delete` are available on it
     *   as  methods with the `$` prefix. This allows you to easily perform CRUD operations (create,
     *   read, update, delete) on server-side data like this:
     *   ```js
     *   var User = $resource('/user/:userId', {userId:'@id'});
     *   var user = User.get({userId:123}, function() {
 *     user.abc = true;
 *     user.$save();
 *   });
     *   ```
     *
     *   It is important to realize that invoking a $resource object method immediately returns an
     *   empty reference (object or array depending on `isArray`). Once the data is returned from the
     *   server the existing reference is populated with the actual data. This is a useful trick since
     *   usually the resource is assigned to a model which is then rendered by the view. Having an empty
     *   object results in no rendering, once the data arrives from the server then the object is
     *   populated with the data and the view automatically re-renders itself showing the new data. This
     *   means that in most cases one never has to write a callback function for the action methods.
     *
     *   The action methods on the class object or instance object can be invoked with the following
     *   parameters:
     *
     *   - HTTP GET "class" actions: `Resource.action([parameters], [success], [error])`
     *   - non-GET "class" actions: `Resource.action([parameters], postData, [success], [error])`
     *   - non-GET instance actions:  `instance.$action([parameters], [success], [error])`
     *
     *   Success callback is called with (value, responseHeaders) arguments. Error callback is called
     *   with (httpResponse) argument.
     *
     *   Class actions return empty instance (with additional properties below).
     *   Instance actions return promise of the action.
     *
     *   The Resource instances and collection have these additional properties:
     *
     *   - `$promise`: the {@link ng.$q promise} of the original server interaction that created this
     *     instance or collection.
     *
     *     On success, the promise is resolved with the same resource instance or collection object,
     *     updated with data from server. This makes it easy to use in
     *     {@link ngRoute.$routeProvider resolve section of $routeProvider.when()} to defer view
     *     rendering until the resource(s) are loaded.
     *
     *     On failure, the promise is resolved with the {@link ng.$http http response} object, without
     *     the `resource` property.
     *
     *     If an interceptor object was provided, the promise will instead be resolved with the value
     *     returned by the interceptor.
     *
     *   - `$resolved`: `true` after first server interaction is completed (either with success or
     *      rejection), `false` before that. Knowing if the Resource has been resolved is useful in
     *      data-binding.
     *
     * @example
     *
     * # Credit card resource
     *
     * ```js
     // Define CreditCard class
     var CreditCard = $resource('/user/:userId/card/:cardId',
     {userId:123, cardId:'@id'}, {
       charge: {method:'POST', params:{charge:true}}
      });

     // We can retrieve a collection from the server
     var cards = CreditCard.query(function() {
       // GET: /user/123/card
       // server returns: [ {id:456, number:'1234', name:'Smith'} ];

       var card = cards[0];
       // each item is an instance of CreditCard
       expect(card instanceof CreditCard).toEqual(true);
       card.name = "J. Smith";
       // non GET methods are mapped onto the instances
       card.$save();
       // POST: /user/123/card/456 {id:456, number:'1234', name:'J. Smith'}
       // server returns: {id:456, number:'1234', name: 'J. Smith'};

       // our custom method is mapped as well.
       card.$charge({amount:9.99});
       // POST: /user/123/card/456?amount=9.99&charge=true {id:456, number:'1234', name:'J. Smith'}
     });

     // we can create an instance as well
     var newCard = new CreditCard({number:'0123'});
     newCard.name = "Mike Smith";
     newCard.$save();
     // POST: /user/123/card {number:'0123', name:'Mike Smith'}
     // server returns: {id:789, number:'0123', name: 'Mike Smith'};
     expect(newCard.id).toEqual(789);
     * ```
     *
     * The object returned from this function execution is a resource "class" which has "static" method
     * for each action in the definition.
     *
     * Calling these methods invoke `$http` on the `url` template with the given `method`, `params` and
     * `headers`.
     * When the data is returned from the server then the object is an instance of the resource type and
     * all of the non-GET methods are available with `$` prefix. This allows you to easily support CRUD
     * operations (create, read, update, delete) on server-side data.

     ```js
     var User = $resource('/user/:userId', {userId:'@id'});
     User.get({userId:123}, function(user) {
       user.abc = true;
       user.$save();
     });
     ```
     *
     * It's worth noting that the success callback for `get`, `query` and other methods gets passed
     * in the response that came from the server as well as $http header getter function, so one
     * could rewrite the above example and get access to http headers as:
     *
     ```js
     var User = $resource('/user/:userId', {userId:'@id'});
     User.get({userId:123}, function(u, getResponseHeaders){
       u.abc = true;
       u.$save(function(u, putResponseHeaders) {
         //u => saved user object
         //putResponseHeaders => $http header getter
       });
     });
     ```
     *
     * You can also access the raw `$http` promise via the `$promise` property on the object returned
     *
     ```
     var User = $resource('/user/:userId', {userId:'@id'});
     User.get({userId:123})
     .$promise.then(function(user) {
           $scope.user = user;
         });
     ```

     * # Creating a custom 'PUT' request
     * In this example we create a custom method on our resource to make a PUT request
     * ```js
     *    var app = angular.module('app', ['ngResource', 'ngRoute']);
     *
     *    // Some APIs expect a PUT request in the format URL/object/ID
     *    // Here we are creating an 'update' method
     *    app.factory('Notes', ['$resource', function($resource) {
 *    return $resource('/notes/:id', null,
 *        {
 *            'update': { method:'PUT' }
 *        });
 *    }]);
     *
     *    // In our controller we get the ID from the URL using ngRoute and $routeParams
     *    // We pass in $routeParams and our Notes factory along with $scope
     *    app.controller('NotesCtrl', ['$scope', '$routeParams', 'Notes',
     function($scope, $routeParams, Notes) {
 *    // First get a note object from the factory
 *    var note = Notes.get({ id:$routeParams.id });
 *    $id = note.id;
 *
 *    // Now call update passing in the ID first then the object you are updating
 *    Notes.update({ id:$id }, note);
 *
 *    // This will PUT /notes/ID with the note object in the request payload
 *    }]);
     * ```
